Universal nonadiabatic energy pumping in a quasiperiodically driven extended system

Zihao Qi,
Gil Refael,
Yang Peng

Abstract: The paradigm of Floquet engineering of topological states of matter can be generalized into the time-quasiperiodic scenario, where a lower dimensional time-dependent system maps into a higher dimensional one by combining the physical dimensions with additional synthetic dimensions generated by multiple incommensurate driving frequencies. Different than most previous works in which gapped topological phases were considered, we propose an experimentally realizable, one dimensional chain driven by two frequencies… Show more

“…This leads to new types of dynamical phenomena, e.g. non-adiabatic topological energy pumps [21][22][23] and prethermalization with algebraically scaling lifetimes [24,25]. However, the absence of time translation symmetry (TTS) is generally expected to generate stronger heating effects, in particular destabilizing localization [12,13].…”
